E = mc2 for the Chemist: When Is Mass Conserved?Richard S. TreptowEinstein's famous equation is frequently misunderstood in textbooks and popular science literature. Its correct interpretation is that mass and energy are different measures of a single quantity known as massenergy, which is conserved in all processes.Treptow, Richard S. J. Chem. Educ.2005, 82, 1636.

A Different Approach to a 3-D Periodic System Including Stable IsotopesAlexandru T. BalabanOn a Periodic System with the two dimensions represented by Periods and Columns, one may stack each stable nuclide of an element along the third dimension. This "Downtown Area" representation is helpful for interconnecting concepts of: element, isotope or nuclide (stable vs. radioactive), atomic weight, atomic number, mass number. Balaban, Alexandru T.

Nucleogenesis! A Game with Natural Rules for Teaching Nuclear Synthesis and DecayDonald J. Olbris and Judith HerzfeldNucleogenesis! is a simple and engaging game designed to introduce undergraduate physics or chemistry students to nuclear synthesis and decay by simulation of these processes. By playing the game, students become more familiar with nuclear reactions and the "geography" of the table of isotopes. Olbris, Donald J.; Herzfeld, Judith. J. Chem. Educ.1999, 76, 349.

Dice Shaking as an Analogy for Radioactive Decay and First Order KineticsEmeric SchultzAn experiment involving the shaking of sets of different sided dice is described. Dice of 4, 6, 8, 10, 12 and 20 sides are readily available. This experiment serves as an easily understood analogy for radioactive decay and for the more general case of first order kinetics.

Determining the solubility of Ca(OH)2 using 45Ca as a tracerEdmiston, Michael D.; Suter, Robert W.These authors have developed a simple lab that can be incorporated into freshman chemistry that allows students to understand the power of radiochemistry as an analytical tool as well as gain perspectives about real versus imagined dangers of radioactivity.Edmiston, Michael D.; Suter, Robert W. J. Chem. Educ.1988, 65, 279.

Variation of radioactive decay ratesWolsey, Wayne C.133. It is stated frequently in introductory chemistry texts that radioactive decay rates are invariant. Students are led to the impression, implicitly, if not explicitly, that changes in chemical form, temperature, pressure, etc. have no effect upon the half-lives of unstable nuclei. This constancy of decay is perhaps true for some particular modes of decay, but by no means is it true for all.Wolsey, Wayne C. J. Chem. Educ.1978, 55, 302.

Some simple classroom experiments on the Monte Carlo methodPara, A. Foglio; Lazzarini, E.In this present paper some applications of the Monte Carlo method suggested to freshmen in nuclear physics and chemistry courses are described. These applications are concerned with radioactive decay, statistical fluctuation of the decay, the slowing of fast neutrons, and the calculation of the ratio of partial cross sections of certain nuclear reactions.Para, A.
